PDF Security Settings

Lock down the PDFs you produce. Set a password for opening the file, or control who can print and edit it, and apply the same rules across an entire batch.

Securing your PDF files might be very important when you work with sensitive information or when you want to protect them from unauthorized use.

1. Open Images

Open one or more files you intend to convert into secured PDFs. Add them manually or use the handy drag-and-drop tool.

2. Add PDF Permissions

Go to the Menu button and click Saving settings → Format saving settings, then go to the PDF tab.

In the PDF Security Settings section you can enter a password for opening the output PDF files and one for allowing various actions applied to it — printing, editing or copying.

3. Save the Result

Finally, choose a location for your output PDFs. For easier access, save them in the source folder, in a newly created subfolder, or in a customized location.

Next, pick the PDF output extension in the lower part of the window and simply press Convert. Your newly secured PDFs will soon be ready!
